Tungsten Carbide Tipped Circular Saw Blades for Non-Ferrous Metals

Accurate, burr free and extremely fast – Saw Blades for Non-Ferrous Metals

High-precision, burr free cuts with fastest speed – this is what BLECHER TCT saw blades stand for. Numerous particular, BLECHER specific manufacturing processes and a blade design that has been tailored to match with the individual cutting job supply the impressive performance and the extremely long service life of BLECHER TCT saw blades. Suited for stationary and flying sawing plants with blade diameter up to 2,230 mm.

Tooth formsApplicationsTypical main dimensionsSawing machineOther options

Tooth forms:

  • triple chip geometry to divide the chip into 3 parts
  • unique “block tooth geometry” for extraordinary surface finish and high cutting speeds
  • chip breaker geometry, preferably for tubes
  • all tooth forms optionally available with C-shaped hook for improved chip forming

Sawing machine:

horizontal and vertical cold sawing machines with high drive capacity, rigid gear box and opening device for the cutting gap, i.e. Framag, Lazzari, Linsinger, MFL, Ohler, Wagner, Asmag, Hertwich, Trennjäger, Kaltenbach

Other options:

  • Single or multiple riveted expansion slots coupled with the SilentCut system as an option supply best possible reduction of noise and vibration to achieve highest cutting speeds

BLECHER QualitY Features

Application oriented selection of blade material

Material selection from a wide range of different alloys and characteristics for application dependent wear life, hardness, stability and toughness, e.g. 51Mn7mod., 75Cr1, 80CrV2, 73WCrMoV2-2, X155CrVMo12-1, S 6-5-2, BLECHER proprietary steel grades BL50, BL55 & BL60/BL80

100% Made in Germany

All materials used for BLECHER saw blades have been made in Germany

Individual tooth geometries

Tooth and cutting edge geometry optimized to each customer-specific application

Tempering with multiple annealing

Technically matured annealing processes with most advanced furnaces, for hardening and (where appropriate multiple) tempering

Cool Grinding

In-house developed “cool grinding” technology with most modern PLC controlled grinding machines reduce heat impact during processing and avoid unwanted residual stress

In-house development

Saw bodies are all engineered, designed and made in house, this ideally matched with each individual application

Consistent documentation

Consistent documentation of all use materials, manufacturing steps and measuring results including from final inspection for each production job

Highest environmental standards

Technically matured annealing processes with most advanced furnaces, for hardening and (where appropriate multiple) tempering

Cutting edge rounding

Brushing process to round the cutting edges which avoids premature tip cracking or the need for running in the saw blade

Thermal stress relieve

Blades are thermally stress relieved to eliminate uncontrollable and unwanted residual stresses from the material rolling process which potentially can create performance deviations during use

Thermochemical platings

Thermos-chemical platings and hard material coatings available for higher cutting speeds and reduced wear

Optimized hardness/toughness

Cutting edge and tip material with optimized hardness, toughness, composition and edge stability as required by the cutting job and the cutting parameters

PLC and pyrometer controlled brazing

PLC and pyrometer controlled automatic brazing for durably reliable welding joints of the carbide tips with no surface hardness increase of the carrier material (saw body)

PLC controlled CBN grinding

PLC controlled CBN grinding of carbide tip pocket seats and tooth geometry with oil cooling for lowest heat impact and continuous precision

Controlled tensioning

Targeted, controlled, reproducible and application oriented blade tensioning guarantees straight cuts with no deviations even across numerous service cycles
